Description

  The present invention relates to an onion leaf cutting machine for cutting a fallen onion leaf on a field.

  The mechanized onion harvesting system varies depending on the working machine used and the scale of planting, but as a system of harvesting work performed by large-scale farmers, rooting work by a rooting machine, by digger After the digging work and the ground-drying, the picking up by the picker and the container filling work (for example, refer to Patent Document 1 below) are performed in this order. Then, as an adjustment operation after harvesting, a tapping / sorting operation using a stationary tapper is performed on the onion in the transported / accumulated container (see Patent Document 2 below).

Japanese Patent Laid-Open No. 10-113025 JP 11-89372 A

  In order to perform the mechanized harvesting work as described above, onions are planted in one to four with a plurality of 4 to 6 strips, and a space for passing tractors and wheels of working machines is secured between the plurality of rows. ing. At this time, since the space between the streaks is set to several centimeters to several tens of centimeters, when the onion leaves grown in the field fall down between the streaks, the onion leaves planted in the adjacent strips are mutually connected. May be intertwined. Such entanglement of leaves tends to occur especially for long-leaved species such as extremely early growth, and when such entanglement occurs, individual onions are separated independently in subsequent picking and tapping operations. There is a problem that it becomes difficult to handle, and good workability cannot be obtained.

  An object of the present invention is to deal with such a problem. That is, the subject of this invention is suppressing the workability | operativity fall of the harvesting work which arises when the leaf of the onion grown in the field falls down between stripes.

In order to solve such a problem, the present invention has the following configuration.
A work machine that is attached to the rear part of the tractor and cuts the onion leaf that has fallen between the lines while moving in the direction of the onion line, and supports the aircraft by grounding across multiple lines. Rotation driven by the power from the transmission unit having an input shaft connected to the PTO of the tractor and mounted on a drive shaft extending in the inter-strip direction, and located between the strips and longitudinally rotated along the moving direction and a cutting blade of the plurality of disc-shaped, the cutting blade is its lower part by working in a state of entering into the ground, characterized that you cut the leaves intertwined between conditions at between Article onions Leaf cutting machine.

  According to the present invention having such characteristics, the cutting blade cuts the fallen leaves between the stripes while moving in the stripe direction, so that the onion leaf grown in the field is adjacent even when the fallen leaves between the stripes. It is possible to cut off the entanglement with the onion leaf planted in the strip, and it is possible to suppress the reduction in workability of the harvesting work due to the entanglement of the leaf.

It is a perspective view of the onion leaf cutter concerning the embodiment of the present invention. It is a top view of the onion leaf cutter concerning the embodiment of the present invention. It is explanatory drawing ((a) is a front view (b) is a side view) which shows the function of the onion leaf cutting machine which concerns on embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same function, and repeated description in each drawing will be omitted as appropriate. In the following description, a tractor direct-mounted onion leaf cutter will be described .

  In FIG.1 and FIG.2, the onion leaf cutter 1 is provided with the body 10 directly mounted on the rear three-point link of the tractor T. That is, the fuselage 10 includes a mounting frame 11 including a mast portion 11A to which a top link is mounted, a lower pin 11B to which left and right lower links are mounted, a fuselage frame 12, and left and right brackets 13.

The onion leaf cutter 1 includes a drive shaft 20 that is pivotally supported by the left and right brackets 13. Drive shaft 20, Article between direction and extends in the (horizontal direction), the cutting blade 21 of the multiple is mounted. The cutting blade 21 is positioned between the onion strips of the onion and rotates vertically along the moving direction of the machine body 10. The drive shaft 20 is rotationally driven by power from the transmission unit 22 supported by the body frame 12, and the transmission unit 22 is an input shaft to which power from the PTO of the tractor is input via a universal join or the like. 22A is provided.

  The cutting blade 21 is driven to cut the onion leaf that has fallen between the strips. In the illustrated example, the shape of the cutting blade 21 is a disk (disk) shape and is a chrysanthemum shape with a recess formed on the outer periphery. However, the shape is not limited thereto, and a flat shape or a saw blade shape without an outer periphery recess is used. It may be a shape or the like.

  The airframe 10 is supported by the ground ring 30. The ground ring 30 supports the rear portion of the machine body 10 by being grounded to a farm scene across a plurality of strips. The grounding wheel 30 is pivotally supported by a wheel frame 31, and the wheel frame 31 has a V shape, one end of which is pivotally supported by the bracket 13, and the other end of which is an upper protrusion of the bracket 13 via a cylinder 32. It is supported by. Thereby, the ground ring 30 is attached to the airframe 10 via the cylinder 32.

  When the cylinder 32 is expanded and contracted, the height of the airframe 10 with respect to the ground plane is adjusted. Thereby, the penetration depth of the cutting blade 21 into the ground can be adjusted by expanding and contracting the cylinder 32.

  A working example of the onion leaf cutter 1 will be described with reference to FIG. The leaf cutting work by the onion leaf cutting machine 1 is performed before or after the root cutting work by the root cutting machine as a pre-processing work of the harvesting (digging and picking up) work. Further, by adding a horizontal root cutting blade behind the bracket 13 of the machine body 10 in the onion leaf cutter 1, the leaf cutting operation by the onion leaf cutter 1 can be performed simultaneously with the root cutting operation.

  As shown in FIG. 3 (a), the leaf cutting operation by the onion leaf cutter 1 is performed by installing the grounding ring 30 so as to straddle the basket P in which the onion W is planted in a plurality of strips, and the cutting blade 21 between the strips. It installs and moves the body 10 along a strip direction, rotationally driving the cutting blade 21. At this time, by setting a part of the cutting blade 21 in the ground of the ridge P, it is possible to effectively cut the fallen leaves between the strips. The penetration depth of the cutting blade 21 into the ground can be adjusted by the expansion and contraction operation of the cylinder 32 as described above.

  By using such an onion leaf cutter 1, it is possible to break an entanglement with an onion leaf planted on an adjacent strip even when the onion leaf grown on the straw falls between the strips. As a result, it is possible to handle the subsequent picking work and tapping work in a state where the individual onions are separated, and it is possible to suppress a decrease in workability of the harvesting work due to leaf entanglement.
